I started having this issue a while ago, when I used pip to install new things. Every time I try to use pip, my command line says: failed to create process. I have checked the system PATH for my Python folder and it seems to be correct. I have tried uninstalling and reinstalling pip several times. I reinstalled Python as well.
Pip commands do work when I put the full path to pip in the command, but I would rather just type pip whatever than pip "C:/path to it" or whatever. Anyone got any fixes or ideas?
I have checked other places where this was answered, and none of the suggestions helped.
Try this & again check path in environment
python -m pip install --upgrade pip --force-reinstall
I have a new Macbook - a user installed it, and then I installed a new user (mine), granted admin privileges and deleted the old one. I am on OS Catalina.
Since the installation I've been having several permission problems.
VSCode can't find Jupyter Notebook, pip installs packages at ~/Library/Python/3.7/site-packages.
When I do which python3 I get usr/bin/python3.
When I do pip3 install <package> I get: Defaulting to user installation because normal site-packages is not writeable And then it says it has already been installed, even though I can't access it when I do import <package>.
It's seems clear that this is a permission problem, pip can't install to the "base" python, and them python can't find what I've installed into ~/Library/Python/3.7/site-packages.
I've tried reinstalling the OS, but since I haven't done a clean install, it didn't change anything.
What am I missing?
How exactly can I fix permissions? Where do I want packages to be installed (venv sure, but some packages I want global (like jupyter).
As #TomdeGeus mentioned in the comments, this command works for me:
Python 3:
python3 -m pip install [package_name]
Python 2:
python -m pip install [package_name]
It's best to not use the system-provided Python directly. Leave that one alone since the OS can change it in undesired ways, as you experienced.
The best practice is to configure your own Python version(s) and manage them on a per-project basis using virtualenv (for Python 2) or venv, possibly via poetry, (for Python 3). This eliminates all dependency on the system-provided Python version, and also isolates each project from other projects on the machine.
Each project can have a different Python point version if needed, and gets its own site_packages directory so pip-installed libraries can also have different versions by project. This approach is a major problem-avoider.
python3.7 -m pip install [package_name]
(you should use the version that you have, of course)
solved it for me.
The most voted answer python3 -m pip install [package_name] does not help me here.
In my case, this was caused by a conflict with the dominating 3.6 version that was also installed as a default. You might ask yourself why you have 3.6 on your system, you will most probably not use that version now. The reason is that 3.6 is used as an independent default python version for many package installers. Those installers do not want to check which individual version you use and whether that fits, they just use 3.6 as a default, if you like it or not.
Here is a proof by example --upgrade pip:
pip3 install --upgrade pip
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pip in
/home/USERNAME/.local/lib/python3.6/site-packages (20.3.1)
python3 -m pip install --upgrade pip
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pip in
/home/USERNAME/.local/lib/python3.6/site-packages (20.3.1)
python3.7 -m pip install --upgrade pip

I'm using Anaconda on Ubuntu and had the same problem.I fixed it by the following steps:
deactivating current environment
conda deactivate
Then, the base environment activates. I deactivated the base conda environment too. To do so, I used conda deactivate again.
Finally, I activate my project environment directly (instead of activating from the base environment) by the following command. Afterward, I installed the intended package successfully and worked perfectly.
conda activate myenv
pip install somepackage
sudo pip install
Worked for me. But pip install is not recommended to be run with sudo. The issue I was facing on BIGSUR was, it was using system python. Once I Installed python 3.9 using
brew install python#3.9
Then pip worked fine
For readers who thought themselves accidentally update system pip:
If you saw this info in your terminal output:
Defaulting to user installation because normal site-packages is not writeable
then you will be fine. Use the pip3 you just updated to run:
pyenv global system # since I use pyenv
pip3 uninstall pip # this one does the trick
Then you can check again pip3 --version will point to the original old (XCode/System-)pip. E.g. (2022/2/28):
pip 20.2.3 from /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)
It occurs with me when I the virtual enviroment folder name was : venv.
in this case, It gives errors like :
No module pip
Default folder is unwritable
renaming the folder solve the proplem.
Check on the command line "which python" to see if it is the value you expect.
If you have a virtual environment activated, check /venv/bin/activate to see the value of VIRTUAL_ENV= and make sure it is the correct path . The path may be wrong if you renamed or moved the project. If the path is wrong, you can delete the venv and make a new one.
For me, none of the suggestions worked so I had to delete the current virtual environment folder venv and recreate it using one of the following commands:
python -m venv venv
python3 -m venv venv
Check the source of pip on Ubuntu 20.04
which pip
returns the correct path
/home/myname/fullstack/person_api/venv/bin/pip
UPDATE
I presume that some might encounter this problem because they set python path as environmental variable like this in ~/.bashrc:
python=/path/to/python
which you should not be doing! Instead we could do:
py=python
PATH=/path/to/python:$PATH
I bumped into this issue specifically because of this!
Had this same issue on a fresh install of Debian 9.12.
Rebooting my server solved the issue.
In my case on Linux, the ownership of the conda env directory had changed to another Linux user (long story), and so the the normal site-packages was not writeable due to a permissions issue.
The solution was to change ownership back to the user doing pip install.
I met exactly the same issue.
I just type sudo python3.8 -m pip install .... and the error disappeared.
If I remove the sudo, issue remains.
For those running on a Pi, that accidentally installed pip as root. Just chown the lib folder to the pi user:
sudo chown -R pi:pi /usr/local/lib/python3.9/
in my case python3 -m pip install [package_name] did not solve that.
in my case, it was a problem related to other processes occupying the directory.
I restart Pycharm and close any other program that might occupy this folder, and reinstalled the package in site-packages directory successfully.
When this problem occurred to me I have tried all the mentioned approaches but they don't seem to work.
Instead, restarting Python language server in my VSCode did the job - my SimPy package is now found. On Mac it is Cmd+Shift+P and select "Python: Restart Language Server".
Had similar issue on Ubuntu 20.04.4 LTS in VirtualBox, but none of the suggestions here worked for me.
I was trying to install open3d in a venv and every time I was getting
"Defaulting to user installation because normal site-packages is not writeable"
which at first I didn't even noticed. open3d was always being installed in /usr/bin/python3 environment. I've restarted the VM but without luck, so I guess the problem was not just missing write access.
So in VS Code, which was using the venv, importing open3d was not possible. But testing from terminal from the activated venv with python3 -c "import open3d as o3d; print(o3d.__version__)" was working fine and that confused me totally. I even broke my system pip installation using sudo, see further below if you want to know how to fix it.
Anyhow, the solution to my problem was to explicitly point to the python3 file in the venv where I wanted to install the package:
venv/bin/python3 -m pip install open3d
So I was testing out everything and eventually installed with sudo: sudo pip3 install open3d. This of course didn't solved the problem and open3d was still missing in the venv. Even worse, I got the message:
"WARNING: You are using pip version 21.3.1; however, version 22.0.4 is available.
You should consider upgrading via the '/usr/bin/python3 -m pip install --upgrade pip' command."
So I did it but with sudo, updating the system pip and then found out here that this is not good:
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
Following an advice here, I tried to revert to original version, only then pip3 broke:
sudo pip3 uninstall pip
sudo pip3 --version
sudo: pip3: command not found
The apt package was still there:
sudo apt install python3-pip python3-pip is already the newest version
(20.0.2-5ubuntu1.6).
So I had to reinstalled to fix the problem:
sudo apt-get remove python3-pip
sudo apt install python3-pip
Maybe you have python, python3, pip or pip3 aliased. In that case pip might not work well anymore, as the alias isn't always available and so pip/pip3 might resolve python/python3 differently compared to in your terminal.
That could give rise to pip/pip3 trying to install in the system python, and that could give rise to your error.
I tried ever single recommendation described here. In every instance, I get the exact same result: SyntaxError: invalid syntax (<stdin>, line 1)
I'm not sure who designed the system like this, but it seems basically useless, based on my experience so far. Either create a system that works, or don't create anything at all.
I'm trying to teach myself python, and I feel out of my depth. To start, I am working on a mac which already comes with python 2.7 installed.
I installed python 3.6 recently and have been using it to teach myself the basics. I'd like to eventually learn how to produce mathematical plots in python, and I know I will need the matplotlib package to do that.
Following some advice online, I was told that python3 already comes with pip installed, which is what I thought I should use to install matplotlib. The advice said I should type the following into the mac terminal:
python3.6 -m pip install matplotlib
I typed this, and it seemed like the package was installing, but I ended up getting some sort of error code that said:
Command "python setup.py egg_info" failed with error code 1 in [folder].
I tried opening IDLE and typing "import matplotlib", but I got the error: "no module named matplotlib". I also tried typing "import matplotlib.pyplot as plt", but I got the same error.
Based on further research and this youtube video, I've decided to just install miniconda in order to have access to the matplotlib package.
The problem is, I'm not sure if I should somehow be uninstalling whatever was installed when I ran the code above to install matplotlib. I've actually run that line of code 3 or 4 times. Should I remove anything before installing miniconda? Also, I am running python 3.6, while miniconda is listed on the website as being for python 3.5. Does this mean it won't work for my version of python?
Running pip like that would install packages system-wide. I'm guessing it's failing because you're not running as root (i.e. the administrator user). But wait! Don't try again as root! Instead of installing packages, do it in a virtual environment. First create it:
virtualenv myenv
This creates a directory called myenv with a bunch of stuff in it (so make note of where you run this command). Whenever you want to use the virtual environment (like straight away!) you first need to activate it:
. myenv/bin/activate
Don't miss out that dot (followed by a space) at the beginning! As the other answer says, the first thing you should do in it is upgrade pip:
pip install --upgrade pip
Now you're ready install whatever else you like:
pip install matplotlib
One last note: The virtual environment is tied to a particular Python version. By default it uses the system's Python 2.7 installation, so to use a different one you need to specify it when you create the virtual environment, like this (if that Python version is installed system-wide):
virtualenv -p python3.5 myenv
Or like this (if that Python version is not installed system-wide):
virtualenv -p /path/to/my/installation/of/python3.5 myenv
While the virtual environment is activated, you don't need to specify the particular path/version of Python. Just run it like this:
python
I also encountered many problems during my installation.
It seems that version 2 of matplotlib is not compatible with Python version 3.
Finally, I succeeded by specifying version 3 of matplotlib as follows with the following command:
sudo apt-get install python3-matplotlib
Reference from the Matplotlib website:
https://matplotlib.org/users/installing.html#building-on-linux
Try upgrade setup tools
--upgrade setuptools
or
easy_install -U setuptools
or upgrade pip
pip install --upgrade pip
I ended up downloading anaconda and using the python interpreter that comes with it, as anaconda comes with matplotlib and many other python packages of interest.
the pip command typically is for the Python 2. use pip3 instead to install the libraries in the python 3.X path
This should work
pip3 install matplotlib
The solution that work for me in python 3.6 is the following
py -m pip install matplotlib
Matplotlib files are downloaded in ~/.local/lib/python3.6/site-packages/ and not in /usr/lib/python3.6/ .
Try the command:
sudo cp -r ~/.local/lib/python3.6/site-packages/* /usr/lib/python3.6/
I am installing python and Django on my shared host server. I have followed the guide located here to install python and pip
http://flailingmonkey.com/install-django-justhost/
As I've encountered the problem of python never using 3.4.2 I've followed a different guide to install python 3.4.2 which is here
http://joemaller.com/1717/building-python-on-shared-hosting/
After I installed python, I went back to follow the first guide to instlall setup tools and pip.
I've ran all the commands it said and when I look inside python3.4.2/bin folder I see pip pip3 and pip3.4 files there so that tells me that pip was installed. However whenever I try to use pip instlal Django it says -bash: pip: command not found. I'm just wondering if I am missing a step somewhere?
The path is set incorrectly so adding so add the following to .bashrc:
export PATH=$HOME/opt/python3.4.2/bin:$PATH
And then source ~/.bashrc.
You could try to write this in consol to install pip
easy_install pip
I recently installed python 2.7.2 on my Mac running OSX 10.6.8. Previously, I had version 2.6. I set my path in .bash_profile as follows:
export PATH=/usr/local/bin:$PATH
export PATH=/usr/local/share/python:$PATH
so that when I run python it will refer to my new installation. It does.
I would also like to use pip with my new installation, but the problem is that I already have the current version of pip installed at
/usr/local/bin/pip.
I tried to re-install pip with:
easy_install pip
But, of course this does not put pip in the desired new directory
/usr/local/share/python/pip
but simply refers to the existing version in /usr/local/bin/pip.
Can someone tell me how to fix this?
I would like to then use pip to install NumPy and SciPy in the correct directory (I was having trouble getting the SciPy installation to work with my old version of python, hence the new install).
If you'd like, you can visit the website where I found instructions for installing python 2.7, creating/updating my .bash_profile, installing pip, and NumPy and SciPy. Might provide some insight, or I'm happy to give more details if needed. Thanks!

Install distribute as per the instructions at http://pypi.python.org/pypi/distribute .
Make sure you specify the full path to the python executable (/usr/local/share/python/python or smth in your case).
$ curl -O https://svn.apache.org/repos/asf/oodt/tools/oodtsite.publisher/trunk/distribute_setup.py
$ /usr/local/share/python/python distribute_setup.py
Then you should have /usr/local/share/python/easy_install.
After that, run:
$ /usr/local/share/python/easy_install pip
Then you should have /usr/local/share/python/pip.
Depending on the ordering of things in your PATH, either your old, or the newly installed pip is executed when you execute the pip command, so you either might have to adapt your PATH, or specify the full path to /usr/local/share/python/pip when installing eggs.
(shameless plug:
In any case, you might consider using virtualenv for installing packages into a "project" specific isolated environment, as opposed to installing them globally.)
I needed to uninstall brew's python.
Then, I was left with python v2.7.6
Next to install, pip I ran
sudo easy_install pip
installed fine and working
I had a similar issue, try this:
$ python -m pip install --upgrade --force-reinstall pip
This will force reinstall pip with whatever version of python you use including installing the binary.
A few days ago I had a friend who was starting Python Programming and needed help with the same issue: installing pip. There are debates over which one to choose between easy_install and pip and it seems everybody is heading the pip direction. Either way, installing either of them can be frustrating.
You can use this simple tutorial : installing pip package manager the easy way
Here are what you should keep in mind as you follow the above guide:
If you already have an older version installed, uninstall it or totally remove the python installation
Once that is cleared, download an install Python.
After that, download ez_setup.py file and save it to your desktop - easily accessible from the command line
Now run it from the command line and it will install easy_install for you after which,
You can use it to install pip.
Once again, you can do this or use the above link to find a simple step-by-step guide on how to get it installed on your computer.
Good luck.
Just so that people knew, ATM we can install PIP by downloading get-pip.py from the page with docs and run it like this:
c:\python27\python.exe get-pip.py
BTW, Python 3.4 comes with PIP pre-installed.
One of the command line options lets you choose where to install to.
--install-dir (-d) install package to DIR
So something like - # easy_install pip -d /usr/local/share/python
(Please correct me if I'm wrong.)
Just wanted to say that I found a way to get around my problem. I don't know that I can explain it perfectly, since I am not very good at understanding what I am doing with this stuff just yet! But, the problem seems to have been with my PATH. I removed the PATH that I posted in my original question, and then used easy_install pip. It went straight to python 2.7.2 (my new version) with no problem. I then successfully used pip to install NumPy and SciPy in the correct location, and they both work. Thanks to ErikAllik and FakeRainBrigand for taking the time to look into it!
